How good is Peerless 850136 as sub driver?

[goldyrathore]

I intend to use two 8" woofers per channel ( two in left front and two in right front) to handle frequencies lower than 300 Hz. I have space of about 0.75 cu ft per driver and will LT eq them to get a response so that there is no need of sub. The usage will be HT as well as music.

How good are Peerless 850136 for this duty? Will I miss the sub?


Thanks,
Goldy

hi

i've just read but i feel that will roll my brain. i don't know what u want really.

They sim nicely in an EBS alignment reaching down to below 30Hz, but require a huge cabinet ~130L.

For a sealed LT the question to be answered is whether you'll run out of xmax, which partly depends on how loud you like your lows...

I like deep clean bass at moderate levels. I mostly listen to rock. My room size is 12 by 20 feet.
I assume that the performance of woofers will be ok for music but am not sure about their performance in HT setup where higher SPLs are required.

goldyrathore double woofer for one channel. it's very much bass in your room(12*20). 2 channels have low frequency increase 6 db.

This is my subjective point of view: If you listen at very low levels, they will be ok. The louder you want, the higher will the lowest possible frequency before distortion or driver damage be. I use four 12 inch woofers in closed boxes with 8mm xmax and i can barely hear a 20hz wave at full excursion. This said, you could just build it and add a sub later, if you feel like having more SPL. By adding a highpass to the 8 inch drivers, you can drive them to higher levels.

With rock music, you have the benefit that it usually has not much content below 40hz, which makes it easier for the woofers.

Depends on how the two 'sub' woofer channels are wired. If all the woofers are driven from a mono system as is usually the case in HT apps, then +6 dB for each doubling of sub systems ('sub' woofer +amp) since input voltage is everywhere the same, but if driven as a stereo pair it's only +3 dB since all you're doing is summing SPLs.
